Apparatus and method for removing DC offset in a frequency direct-conversion device |
摘要 |
An apparatus for removing a DC offset during frequency direct conversion in a reception device of a wireless communication system. In the apparatus, an adder receives a digital baseband signal comprising a DC component, receives an estimated DC offset value, and calculates a difference between the digital baseband signal with the DC component and the estimated DC offset value. A DC offset calculator receives gain mode information of an analog element of the reception device, and calculates the estimated DC offset value according to the gain mode.
